What Is Weldment Fabrication?

 

In metal production, welding is the process that applies heat to metal parts and then uses a filler to form a joint. Weldment fabrication is joining two or more metal pieces into one cohesive piece. Having an adequately tested design prototype helps determine the kind of weldment required.

The performance of a welded structure is tested by checking and correcting common faults, such as:

  • Improper metal fusion
  • Porosity in the weld metal
  • Undercutting on the base metal

Typical Metal Fabrication Processes AdobeStock 83134625

Raw metal passes through a few operations before the final product is client-ready. For example, before an automobile frame reaches the assembly plant, it typically goes through some, if not all, of the following metal fabrication processes:

  • Cutting freshly-made pieces of metal or pre-shaped bars into desired sections using such items as high-tech laser cutting machinery or plasma torches.
  • Folding sheet metal using a press brake or an auto-robotic bending machine that manipulates it into specific angles for the desired shape.
  • Welding is a process that uses heat application to join metals and separate pieces of sheets or panels.
  • Punching involves sandwiching sheet metal between a die and punch-through to create customized contour shapes or holes, sometimes using a process referred to as nibbling.
  • Shearing utilizes a blade controlled by a squaring arm to create precision cuts on metal materials like iron, steel, aluminum, copper, and bronze.
  • Stamping fabrication uses a die to form intricate shapes, images, or letters on a metal panel, as seen in coins.
  • Casting is where molten metal such as gold, silver, steel, or iron is poured into a pre-formed mold and allowed to solidify into a specified form.

Some fabrication facilities may offer specialized metal finishing services, including blackening, cladding, grinding, plating, and powder coating. They are often the last machining operations based on aesthetics.

Commonly Used Welding Methods in Metal Manufacturing

Welding involves a few moving parts to ensure the longevity, integrity, and aesthetics of a weldment centered on industry codes and standards. Depending on the project, some welding facilities apply high-tech lasers, electromagnets, and microwaves. They may also use a simple torch or forge method.

Although there are numerous welding methods, the four most common include:

  • MIG Gas Metal Arc Welding (GMAW) – utilizes an electric arc to heat metals such as carbon steel, stainless steel, aluminum, and copper to their melting point to form a permanent bond. MIG welding is employed in automobiles’ manufacture, repair, and maintenance.
  • TIG Gas Tungsten Arc Welding (GTAW) – uses a consumable tungsten electrode, a rigid metal material that doesn’t burn off or dissolve. Because welding TIG also utilizes helium or argon as an external gas supply, it’s primarily applied in the aerospace and automobile industries.
  • Stick Shielded Metal Arc Welding (SMAW) – uses a protected welding electrode covered with a thick coating of flux that burns while creating a protective cover between metal pieces. Stick welding is ideal for creating hard surfaces on farm equipment.
  • Flux-Cored Arc Welding (FCAW) – combines a base metal power supply and a continuous hollow flux-filled electrode fed through a welding gun into a weld pool. Given that this type of welding provides exceptional penetration, it’s applied in industrial machining to thick weld steel. welding iron spark fire hot steel with power GMAW welder

Industries That Commonly Use Welding in Their Fabrication Process

Below is a list of industries that rely on welding for their fabrication process:

  • The automotive industry turns to MIG welding to manufacture, assemble, and repair all types of vehicles.
  • Aerospace depends on laser MIG, plasma arc, or electronic welding for manufacturing aircraft and performing precision work during the repair and maintenance of all flying crafts.
  • Infrastructure and construction use plasma arc, shielded, and flux-cored welding for building roads and bridges, including commercial and residential properties.
  • The shipping and railroad industry employs electric arc, gas pressure, and thermite welding processes in constructing, repairing, and maintaining cruise liners, ships, railroad tracks, etc.
  • Manufacturing is another industry that utilizes MIG as a standard welding process to produce computer components, furniture, mining machinery, and agricultural tools.

Final Thoughts

With raw material versatility and the assurance of strength and permanence, welding provides numerous benefits that outweigh other methods for joining or fastening disparate elements.
